[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 4 This application provides a wastewater treatment filter bar, including a treatment tank 1. A cleaning component 3 is disposed inside the treatment tank 1, and a moving component 2 is disposed outside the treatment tank 1. The cleaning component 3 includes a support plate 31 and an internal platform 37. The internal platform 37 is fixedly installed inside the treatment tank 1. A bar 4 is fixedly installed inside the treatment tank 1, with the right side of the bar 4 being higher than the left side. The lowest point of the right side of the bar 4 is fixedly installed on the top left side of the internal platform 37. A collection trough 34 is formed inside the internal platform 37, and the inside of the collection trough 34 is arc-shaped. The left side of the collection trough 34 is flush with the bottom of the bar 4. Two side plates 35 are fixedly installed at the bottom of the support plate 31, and a cleaning hopper 36 is rotatably connected between the two side plates 35. The outer diameter of the cleaning hopper 36 is the same as the inner diameter of the collection trough 34, and the center lines of the cleaning hopper 36 and the collection trough 34 coincide.

[0026] An internal rod 38 is fixedly installed between the inner sides of the cleaning bucket 36. The internal rod 38 is located between the front and rear walls of the cleaning bucket 36, and the center of the cleaning bucket 36 coincides with the center of the internal rod 38. A hydraulic motor 33 is fixedly installed on the front of the side plate 35. The output end of the hydraulic motor 33 moves through the interior of the side plate 35 and is fixedly connected to the cleaning bucket 36. Side grooves 32 are opened on the front and rear inner walls of the treatment pool 1, and the side plate 35 is located inside the corresponding side grooves 32.

[0027] In this embodiment, when the screen 4 is in use, sewage is discharged above the screen 4 through an external pipe. The screen 4 filters out large particles of impurities in the sewage. After being filtered, the sewage flows through the treatment tank 1 to the next process. The impurities, after being processed, fall into the collection tank 34 on the right side under the guidance of the screen 4. The collection tank 34 collects the impurities. As the impurities gradually accumulate, some of the sewage accumulated in the collection tank 34 is replaced by solid impurities. Most of the impurities remain in the collection tank 34, greatly reducing the probability of impurities accumulating on the screen 4. When the impurities in the collection tank 34 need to be cleaned, the hydraulic motor 33 is started to drive the cleaning bucket 36 to rotate around the side plate 35. When the cleaning bucket 36 rotates, it will rotate into the collection tank 34 and scoop away the impurities in the collection tank 34 along the inner edge of the collection tank 34. When the opening of the cleaning bucket 36 faces upward, the impurities in the collection tank 34 can be completely scooped into the cleaning bucket 36, thus achieving the effect of convenient impurity cleaning.

[0028] Reference Figures 1 to 4 In one aspect of this embodiment, the moving assembly 2 includes a moving plate 25, a hydraulic rod 26 fixedly mounted on the top of the moving plate 25, the output end of the hydraulic rod 26 movably penetrating the interior of the moving plate 25, and a support plate 31 fixedly mounted at the bottom of the output end of the hydraulic rod 26. The moving assembly 2 also includes a bracket 21, a horizontal plate 22 fixedly mounted on the top of the bracket 21, an electric slide rail 23 fixedly mounted on the bottom of the horizontal plate 22, and a track slider 24 slidably connected to the outer bottom of the electric slide rail 23, the track slider 24 being fixedly mounted on the top of the moving plate 25.

[0029] In this embodiment, after the impurities are cleaned into the cleaning hopper 36, the hydraulic rod 26 is activated to move the support plate 31 upward. The side plate 35 then moves the cleaning hopper 36 upward and out of the treatment pool 1. After it is moved out, the electric slide rail 23 is activated to move the track slider 24. The track slider 24 moves the cleaning hopper 36 to the outer flat ground. The hydraulic motor 33 then flips the cleaning hopper 36 to clean out the impurities inside, further ensuring that the impurities are easily cleaned.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: When the screen 4 is in use, sewage is discharged above the screen 4 through an external pipe. The screen 4 filters out large particles of impurities. After passing through the screen 4, the filtered sewage flows through the treatment tank 1 to the next process. Impurities, after being processed, are guided by the screen 4 and fall into the collection tank 34 on the right. The collection tank 34 collects the impurities. As the impurities gradually accumulate, some of the sewage accumulated in the collection tank 34 is replaced by solid impurities, leaving most of the impurities inside the collection tank 34, greatly reducing the probability of impurities accumulating on the screen 4. Furthermore, when the impurities inside the collection tank 34 need to be cleaned, the hydraulic motor 33 is activated to drive the cleaning bucket 36 to rotate around the side plate 35. As the cleaning bucket 36 rotates, it will reach the collection tank 34. Inside the 4th chamber, the cleaning bucket 36 scoops away the impurities inside the collection tank 34 along the inner edge of the collection tank 34. When the opening of the cleaning bucket 36 faces upward, the impurities inside the collection tank 34 can be completely scooped into the cleaning bucket 36, thus achieving the effect of convenient impurity cleaning. After the impurities are cleaned into the cleaning bucket 36, the hydraulic rod 26 is activated to drive the support plate 31 to move upward, thereby moving the cleaning bucket 36 upward and out of the treatment tank 1 through the side plate 35. After being moved out, the electric slide rail 23 is activated to drive the track slider 24 to move. The track slider 24 moves the cleaning bucket 36 to the outer flat ground, and the hydraulic motor 33 is used again to flip the cleaning bucket 36 to clean out the impurities inside the cleaning bucket 36, further ensuring the purpose of convenient impurity cleaning.
